To all whom il may concern:

Be it known that l, (inoaoe W. Sg'rlin, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have made rertainncw and :isefnl Improvements in Windowventilators, of which the following is a specification.

My invention relates to improvements iu means for ventilating windci. and it consists in the combinations, constructions and arrangements herein dimcrihed and claimed.

An object of my invention is to provide a device in which good ventilation is secured while at the same time the ventilating opening is shaded without the necessity of using a prtg'ecting awning or other simi ar device.

irthor object of my invention is to provide a ventilating device which while permitting ventilation reventa tne rain or snow m entering whi e the device is in use.

A further object of my invention'is to provide means for dircctin the incoming current of air so that it will directed up- A irther object of m invention is to rovide a ventilator wliic may be readily etached or replaced when occasion requires.

A further object of my invention is to provide a Ventilating device having retaining slides which act as slpring sash holders thereby keeping the wm o sash from rattling or working loose.

Other objects and advantages will appear in the following specification and the novel features of the device will he particularly pointed out in the a pendcd claims.

My invention is i ustrated in the accompanying drawings in whic Figure 1 is an inside view of a window equipped with my improved ventilating device; Fig. 2 is a sectional view along the line 2-2 of Fi l; Fi 3 is a side view of the outside of t e win' ow; Fig'. 4 is a fragmentary detail lview in perspective of the upper ventilating plate; Fig. 5 is a detail view in perspective showing the arran ement of t e metal retaining strips; and I' ig. 6 is a fragmentary view in perspective of the lower ventilatin plate.

In Figs. 1 and 3 have shown the inside and outside respectively of an ordinary window consisting of a window frame A and the upper ainl lower .wishes l! and (l res|x-rtively. 'lhe window frame A is provided with thc usual run-ways D itnd E for the sashcs C nml B as shown in Fi 2 and theaa runways are separated b t ie dividing stri F. 'l`o the lower part oi' the inner side o the frame A, l secure the retaining members U. These retaining ineinhers comprise a llat strip i; having integral portions y' bent back paral el with the main portion (i and laterally extending portions g which are attached direct ly to the sides of the casing A a.- rlearly shown in Fig. 5. Secured to the lower part of the retainin member G is ai; inclined supporting strip fl. These retaining members constitute slides for holding thc lower ventilnting plate K as shown in l Fig. l, as will be hereinafter explained.

lhe meansby which the lower outside ventilating plate L is secured is shown also in Fig. i, it heilig understood that both the retaining members (i and M shown in this ligure are duplicated on the opposite side of the window so that a description of one Set will sutlice for both. The retaining member M consists of a tlat portion m which is secured to the bottoni of the run-way D and The flan 'e l lies in ii ciit-awiiy iortion Q of the divi in v strip F, which wil insertion o? the ventilating plate i between the flange l and the ed of the dividing stri F as will be hereinater ex laincd.

'l ie three vcntilating plates l. and R forming the main subject of this invention are clearly illustrated in the heures.

Rcferrin r now to Fig. L. it will be seen that the piite l. which i.- intended for thc outside of the window consists of a single sheet of metal from which are punched the rta'tangular portions I, these portions being heut outwari lv to forni projecting strips for the openings .\t the hottoin of the strip there is a lateral llange while the top is lient over at l to clamp the u per edge of a screen l secured thereto. T ic lower end of the screen is secured to the lower edge of the plate l. h v 'soldering or in any other suitable nuinner. 'lhe ends of the flange l2 are cut away as shown `at I".

'lhe "nner lower Itrip I( and the upper st rip Il an` somewhat .-'iiniliir in construction. These plate.- are provided with a .-eries' of portion which art` relatively Small in entitiari-'on with the strips l lait which like thc lutter :ire pululu'd from the plato :tml are lient in an angular direction uli-arly .-liown in l"i; l. 'l'lio upper platill i.- provided with :i lati-rally extending tlaugr r t'or :it-

is providedvwith un integral lateral tlange P.

`rmit the ino tachnient to the window cming, while the lower late is provided with a similar llaiige il', aoc `ig. for attachment to the lower part of the window frame A.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. e

The upper strip It is preferably secuml in the run-way c, the flange i' being disposed in the nin-way and secured to the top thereof by screws or nails as clearly shown in l"i 2. The main portion of the plate Il lies in ii cut-away portion r' of the outside frame A so as to resent a smooth surface to the window The lower outside Ventilating plate iuay be inserted in theslots Q between the o posed members P and F, and swing to t ie cut-awa portion l into which the ange P enters ie plate may be lowered into the position shown in Fig. 2 and there secured by a pivoted catch which hooks over the flange l or it may be secured directly to the frame A by means of screws or nails.

The inner lower plate K may be inserted between the members g and g of the retaining member G and it also ma be secured by a pivoted retaining latch or be perinanently secured as described.

A window thus equipped bas the followadvanta The lower sash may be raised and the window left up even during a rain storni without danger of injury to the interior of the room by the rain beating in through' the window. The inclined strips l of the outer lower ventilating plate L prevent tlie entrance of the rain or snow iv iile freely admitting air. Thevscreen attached to the lower plate prevents the entrance of insects. Moreover, the inclined' late l shades the window so that the glaring sun liht is prevented from entering. The inner p te K is perforated in such a manner as to permit the entrance of air but to deflect it upwardly atan angle so tlnit a person sittin near the window is not in the direct draft. The upper outside late Il being provided with t e downward y projectin poi-tions r prevents the entrance of rainw iile permittinf the escape of air.

t. will be observed from the similarity of construction that the lower inner plate K ma be used in lien of the upper outer plate It v reversing the position of the lower plate and attaching it in the'nianner shown in Fig. 2 on the upper outside of the window in place of tlie plate. It. The upwardlyint-lined punched portions of the plate K will then be downwardly inclined siiniliir to the iunchcd portionei'r' of the plate R and wil consequently serve the same purpose.

I am aware that other forma of the device based upon the same neral principle might be made but I consi er as in own ali such modifications as fairly fall within the spirit and scope of the invention.

I claim:

l. In a window ventilating device, an outside Ventilating member comprising a single sheet of iiictal having rectangular portions punched therefrom to forni ventilatiug openings, said portions formin' shades for the openings in combination with an inside vcntilating device arranged to detlect the air coming from the outside ventiliitor in an upward direction.

2. in a window ventilating device, the combination with a window frame, of retaining strips secured thereto, an outside ventilating plate slidably held by said retainin strips, said ventilating plate being provi ed with shaded openings and an inside ventilatiug plate rovided with perfora tions and an indivi ual air detlector for each rforation.

3. n a window ventilating device, the combination with a window frame, of retaining strips secured to said frame, a lower ventilating plate slidnbly held b said retaining strips and provided wit a series of openin each opening being shaded by an inclin grotecting str'p and a screen secured to sai ventilating late on'the opposite side from said inclined) protecting strips.

4. In a window ventilating device, a ventilatiiig plate comprising a rectangular strip of a length a proximating the width of the window, sai strip being provided with a series of rectangular openings *ormed by punching portions from said strin, said portions being bent outwardly and disposed in angular relation to the niain body portion, the upper edge of said strip being turned over and a screen secured to the side of the ventilatinfr strip opposite the punched portions, sai screen ing held at its upper edge by said turned over ioi'tiou.
